Charleston Masonry Repair involves targeted fixes to prevent damage that can grow into larger scope projects like restoration. This can include tuckpointing (repairing mortar joints), replacing damaged bricks, or sealing structures.

Taking care of brick masonry early through regular maintenance can help prevent problems in the future, especially when it comes to leaks or other moisture damage. Learn more about the five most common causes of brick masonry repairs.
Brick walls are relatively resilient structures, but like any material they can become damaged over time. Brick damage can range from cosmetic to structural, and it is important to address problems promptly to prevent further deterioration or costly repairs. Regular inspections are the best way to catch problems early and address them before they become worse.
Small cracks and chips in brick walls are easy to fix, but they are often overlooked because they don’t appear as serious as other damages. However, ignoring these small issues can lead to larger problems that require more extensive and costly repairs.
Before starting any repair work, it is crucial to clear away loose debris and dust from the area. This step will help to ensure that the new mortar adheres properly and is a strong, long-lasting repair. Once the damaged areas are clean, the mortar can be mixed according to the manufacturer’s instructions. Once it has been mixed, it can be applied to the bricks using a trowel or tuckpointing tool. Care must be taken to ensure that the mortar is filled completely and evenly.
Once the repaired area is dry, it is important to inspect it for any further issues. This can include any lingering mortar or brick chips, as well as checking for cracks in the load-bearing walls of the structure. Cracks in load-bearing walls can cause serious structural problems, and should always be assessed by a professional to determine the root causes and appropriate course of action.
Other common problems that need to be addressed are efflorescence (white, powdery salt deposits) and staining on the surface of the bricks. These can usually be removed with a stiff brush and water, although in some cases a specialist cleaning service may be required for particularly stubborn stains.
Finally, if steel lintels have been fitted to support bricks above doors and windows, they can become damaged over time, especially when the masonry is subjected to extreme temperatures. Lintels can also deflect when they are fastened to wood framing that expands and contracts more than the masonry itself.
Loose or Cracked Mortar
Loose or cracked mortar can allow water to seep into the space between bricks. This moisture can cause mould, mildew and wood rot, which are difficult to get rid of once they start developing. Tuckpointing is a great solution for this problem because it seals the cracks and prevents water from damaging the masonry structure.
If left untreated, these cracks can progress to more severe issues that require structural engineering review. A professional masonry contractor can assess the situation and recommend an appropriate course of action for your home.
Once the damaged mortar is removed, a new bond can be created between the bricks. During this process, it’s important to take your time and follow the correct steps to ensure a long-lasting repair. First, the stone wall surface should be cleaned thoroughly using a stiff-bristled brush to remove any dirt, debris or loose mortar. Next, the mortar mix must be properly mixed to the recommended consistency. The mix can be adjusted depending on your stone wall type, but is usually comprised of 6 parts sand and 1 part cement. Finally, the new mortar must be applied to the joints using a trowel and carefully packed. Once the joints are filled, it is necessary to tool the mortar with a pointing tool to create a smooth finish.
During the curing process, it is important to protect the repaired area from direct sunlight, rain and extreme weather conditions. It is also a good idea to mist the area daily with water to keep it moist, which promotes proper curing and strengthens the bond.
After the mortar has cured, it is important to periodically inspect the masonry for any signs of damage or movement. If any problems are noticed, they should be addressed immediately to prevent further issues. Additionally, it is a good idea to use a breathable masonry sealant on the repaired areas to protect them from moisture penetration and extend their lifespan.
Brick Spalling
Brick spalling occurs when a portion of brick and mortar breaks off from the surface of the wall due to moisture damage. This condition can be extremely dangerous, especially in older brick homes where it can occur throughout a structure. Brick spalling can be caused by many different things, including exposure to freezing and thawing water, rain and wet soil. It can also be caused by improper mortar or pointing, sandblasting or pressure washing and use of harsh chemicals.
If a brick is spalling, it must be repaired by an experienced mason to ensure that the new masonry work is durable and matches the appearance of the surrounding bricks. A mason can repair the damaged brick by removing the old mortar and replacing it with lime-based mortar. They can also add character marks to the new mortar using tools like forks or chisels to give it the same appearance as the existing brick.
A masonry professional can also help prevent spalling by identifying the cause of the problem and taking steps to minimize moisture infiltration. For example, they can install gutters and downspouts, improve drainage in the soil around the masonry structure, and consider installing a dehumidifier for basements. They can also test cleaning products before using them on a brick surface to make sure that they don’t cause any further damage.
The extent of the repair required will depend on the severity of the spalling. For severe cases, it may be necessary to replace the entire section of the wall. In this case, it’s important to choose replacement bricks that are the same size, texture and color as the existing bricks. Once the damaged bricks have been removed, it’s important to clean the area thoroughly before laying the new bricks. This will help to reduce the likelihood of future damage caused by moss and algae growth, mold and mildew formation, ice and snow damage and excessive water absorption. It’s also a good idea to apply a breathable sealant to the brick wall after it has been cleaned and treated. This will help to reduce the moisture absorption that can cause spalling in freezing temperatures.
Damaged Lintels
Lintels are crucial components positioned above windows and doors, supporting the weight of building materials above. They aren’t indestructible though, and factors like exposure to moisture, corrosion and shifting foundations can cause damage. Effective lintel repair can prevent costly structural damage and wall collapse. Look for signs of deterioration such as cracks above openings, rust stains and movement of brickwork above the lintel.
Masonry repair experts can identify the root causes of lintel damage and recommend targeted repairs. If the lintel is in good condition but the surrounding brickwork has suffered damage, the professionals can tuckpoint the affected area to repair the masonry and restore the structural integrity of the building.
In cases where a lintel is damaged beyond repair, replacement may be required. This is a job that should only be undertaken by a professional who can safely distribute the weight of the building off the new device. A galvanized steel lintel is generally recommended, as it is durable and will not corrode in the future.
When a lintel is replaced, it’s important that the replacement be done at the same time as other masonry repairs because otherwise the new lintel will quickly become damaged from stress on the surrounding brickwork. This is why it’s essential to choose a professional with extensive experience in all aspects of masonry restoration and waterproofing.
It’s also a good idea to have a professional examine the brickwork around a lintel on a regular basis, so that problems are identified early and acted upon before they become serious.
Small cracks in a brick or concrete wall are common, and can be repaired with simple methods like tuckpointing. Larger cracks in critical areas of a brick or stone structure, on the other hand, can be a sign of much more serious underlying issues. If left unattended, these cracks can lead to significant structural damage and a potential collapse of the entire wall. The key is to be proactive in identifying any damage and making repairs. This will keep your home or commercial building safe and prevent expensive repairs in the future.
